You can view what forecast runs are part of the active forecast from the Forecast Run Details section of the Modeling module. You can view the individual model alternatives for a forecast run. By default, the first forecast run displays in the Map Window and the name of the forecast run is bolded in the Forecast Run Details section, the forecast run is being displayed in the active Map Window of the Modeling module. 

Forecast Run Details

When the box next to a forecast run is checked, you can view output from the run using the model schematic displayed in the Map Window. In this version of CWMS, the only software application that displays output results for multiple forecast runs is HEC-ResSim. In addition, the time series icons will display output for multiple forecast runs. MFP will display separate summary reports for each forecast run.

Forecast Runs – Shortcut Menu

From the Forecast Runs Detail section of the Modeling module, a shortcut menu will display when you right-click on a forecast run name. From this shortcut menu, you can perform many processes.

Model Alternatives – Shortcut Menu

Under each forecast run name is the list of model alternatives associated with the forecast run. When you right-click on a model alternative name, a shortcut menu will display. The example below is the shortcut menu for an HEC-HMS model alternative. 

HEC-HMS Model Alternative Shortcut Menu

From the shortcut menu you can compute individual model alternatives by clicking Compute. You can also identify whether you want a model alternative to be skipped during a forecast run by choosing Skip Compute from the shortcut menu. The icon of the model alternative being skipped will now have a blue arrow pointing down drawn through it, and the Skip Compute item in the shortcut menu will show a checkmark.

HEC-HMS Model Alternative - Skip Compute Blue Down Arrow

To have a forecast run compute through a selected model alternative, select Compute Through from the shortcut menu. The icon of the model alternative will now have a red line and a red up arrow drawn through it, and the Compute Through item in the shortcut menu will show a checkmark.

Model Alternative Map Schematic Element – Shortcut Menu

You can expand a model alternative and display the map schematic elements associated with that model alternative. When you right-click on an element, a shortcut menu will appear. Depending on the model alternative and the map schematic element, the shortcut menu will provide different options. Additionally, the selected element will be highlighted on the Model Schematic that is displayed in the Map Window.
